CABLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 612,575, dated October18, 1898.

Application filed September 15, 1897- Serial No. 651,804. (No model.) i

To all whom it may concern:

Be it known that'l, ROY SIMOT, a citizen of the United States, residingat I-Iolton, in the county of Muskegon and State of Michigan, haveinvented a new and useful Cable-Stopper, of which the following is aspecification.

My invention relates to improved mechanism for gripping at any desiredpoint a rope or cable having a weight suspended from one end thereof,commonly known as cablestoppers and the invention is especially designedand applicable to stump or tree moving machines.

It is adapted to provide for instantly and automatically securing theelevated stump or weight the moment the raising chain or cable ceaseslifting the same or the movement of the chain or cable isstopped and tohold the weight or stump thus suspended in readiness for removal to itsfinal destination; also, to

provide for the ready release of the raising or lifting chain or cableto allow the lowering of the stump or weight to the ground and to allowof the independent lateral movement of the front bolster and axle,permitting the latter to tip up and down,as circumstances require.

The invention therefore consists of automatically gripping or engagingjaws adapted to act on the weight or stump lifting or raising chain orcable and means for readily disengaging or releasing said jaws.

The scope of my invention extends, as above indicated, to means forautomatically and instantly gripping or securing the weight raising orelevating chain or cable when the latter is under strain or stress atthe instant the pull or strain on said chain ceases, comprisingspring-actuated jaws arranged upon a carrying frame or truck, one uponeach side of said chain or cable; secondly, to means in the form of aspring-lever connected to one of said jaws to shift or laterally movesaid jaw away from the opposite jaw and automatically return said jaw toits engaging or original position. Other parts associated with thesefeatures will be treated as incidental to the invention and as means toan end.

In the accompanying drawings, disclosing tion, Figure 1 is a side viewof the invention ism.

as applied to a frame and hoisting mecham Fig. 2 is a frontview of aportion of said frame, showing the complete mechanism. Fig. 3 is asectional view 011 the line as: w of Fig. 2. Fig. 4 is an enlargeddetail view of the gripping-jaws, and Figs. 5, 6, and 7 are details ofconstruction.

A suitable carrying-frame comprising in its general construction ahorizontal subframe D, secured upon front and rear leg portions 0 O, ismounted in the rear upon wheels B and in the front upon" correspondingwheels B. The sundry individual or detail parts of the carrying-frame,such as cross and cliagonal braces and connecting-pieces, need not bereferred to herein, as the same are as would suggest themselves in theputting together of the principal or main members of saidcarrying-frame.

The front uprights or leg portions 0 of the carrying-frame are braced orconnected by any suitable means, preferably the U shaped metallic pieceor brace I, secured to the rear side thereof in any suitable Way.

Between the leg portions 0 is secured a back portion M, faced bya plateH, fastened to the front sideof said portions 0, said lblock portion andplate having coincident openings therein to provide for the passagethere through of the weight or stump lifting chain or cable 10, a pulley11 being hung in the opening in said block, under which said chain orcable passes. The chain 10 has one end suitably secured to a cross-pieceaof the portion D of the carrying-frame and is thence passed over apulley d, suitably hung from a second cross-piece a of said portion ofsaid I frame, and over a second pulley cl, similarly hung in position asthe aforesaid pulley. Intermediary of the pulleys d d, however, saidchain or cable is passed under and suspends a pulley and block 01 ascommonly practiced,

said block and pulley having suspended therefrom grappling-hooks 61 witha chain d", to efiect suitable connection with a stump or weight orother body to be elevated.

F F are suitable jaws, rectangular in their general construction, hungor pivoted upon the front side of the plate H, one at each side of thechain-opening therein, with the pintles I) 11, upon which theyare hungor pivoted,

passing therethrough from end to end, the edges of said pintles beingcarried through said plate and screw-threaded portions engaging nuts onthe rearside thereof as a preferable way of securing said pintles inposition. These pintles are sufliciently extended at their upper endsabove the jaws F to provide for the application thereto of coiledsprings h h, with their ends secured or connected to said jaws andbearing upon said plate H, respectively, to put said jaws under pressureand cause them to automatically grip or engage the lifting chain orcable 10, passing through the opening in said plate and itsbacking-block, as seen in Figs. 2 and 4. The pintle of one of the jaws Fhas its lower end let into a lateral slightly upwardly inclined slot 0in the plate H to permit that end of the jaw to also have lateralmovement or be moved away from its fellow jaw,whereby the grip of thejaws upon the lifting chain or cable may be released.

G is a hand-lever pivoted at its lower end to the plate H and connectedby a link g to a clasp g, compassing or sleeved upon the pintles of thelaterallymovable one of the jaws F F to provide by the requisitemovement of said hand-lever for the convenient lateral movement of saidjaw for the purpose aforesaid. Said hand lever is held by a spring 9connected thereto and to the plate H, so as to automaticallyreturn thelaterallymovable jaw to its original ornormal position after the releaseof said hand-lever.

The rear side of the chain passage or openi for normally forcing saidjaws together, and means for moving one of said jaws laterally in adirection opposite that of the tension of the springs to separate thejaws, substantially as described.

ing in the block M maybe guarded, as shown at m in Fig. 4, to cause thechain to maintain its proper relative position to the pulley 11, underwhich it passes, as aforesaid.

It will be observed that after having suitably grappled the stump orweight upon winding the lifting-chain 10 or pulling upon itit may be byhitching a horse thereto, as usual-said stump or weight will be elevatedor lifted, and thus held by the gripping action of the jaws F upon saidchain, the jaws instantly and automatically-gripping the chainthe stumpor weight can be lowered to the ground and be ungrappled, the machinethen being ready for a like operation.

Having thus fully described the invention,

The machine is now.

what is claimed, and desired to be secured by Letters Patent,is-

1. In a cable-stopper, gripping-jaws, one adapted to have lateralmovement at its lower end in a direction opposite that of the grip, anda hand-lever connected to said laterallymovable jaw and adapted to beautomatically returned with said jaw to its original position,substantially as described.

2. In a cable-stopper, the combination of the opposed jaws hung uponpintles suitably secured in position, springs applied to said pintlesand adapted to hold saidjaws under pressure, said jaws adapted toautomatically grip the lifting chain or cable, substantially asdescribed.

3. In a cable-stopper, the combination jaws hung upon pintles suitablysecured in position, one of said pintles arranged in a lateral slot, andthe spring-held hand-lever connected by a link to a clasp compassing orsleeved upon the pintle arranged as aforesaid, substantially asspecified.

at. In a cable-stopper, the combination of the opposed jaws arranged 011pintles springs attached to the pintles adapted to exert pressure uponsaid jaws, one of said pintles arranged in a lateral slot, a hand-lever,a link 5. In a cable-stopper,opposing jaws, springs 6. In acable-stopper, spring-actuated opposing jaws hung upon pintles suitablysecured in position, an offset at the end of one of said pintlesengaging a slot to permit of the lateral movement of one of the jaws,and

'means for separating the jaws, substantially as described.
